I am using the dev force sample code for configuring winforms.

I have adapted it to my database. Which is rather large 6000+ customers.
I want to search for a customer (based on 'lastfirst' field is fine)
I would like to know the best practise for this.

where do I put the code... in the Custom control or in the tab page??

If you're using the solution from the "Composing WinForms with UserControls" solution, that one lets the TabPage handle construction of the data retrieval query. It then passes that query to UserControl's LoadMainData() method.
 
Here, for example, is the LoadData() method from the EmployeeTabPage. Note the highlighted line:
 

public override void LoadData() {

_orderUserControl.LoadSupportingData();

_employeeUserControl.LoadSupportingData();

EntityQuery<Employee> anEntityQuery = _entityManager.Employees;

_employeeUserControl.LoadMainData(anEntityQuery);

}
